Is there any way to bind arrow keys to WASD in pico 8, like you can in Picotron? I understand that Picotron has to deal with text input as-well as other controls, but given how common a WASD control scheme is, I feel like there should be some compromise, especially give that, if the cart doesn't rely on text input, there should be no code or gameplay changes needed if Picotron just remapped the btn(0) to btn(3) functions to WASD.

I think it maps a secondary directional stick to wasd! You could mess around with the Picotron Controls Reference to see exactly what things are mapped to

Yeah, my main issue with that is that it requires support from the dev that isn't always present. really, a program like keyconfig is what I'm looking for, either that or something in the config.
